Lookalikes: [[17edo]]
== Theory ==
10edf is related to [[17edo]], but with the [[3/2|perfect fifth]] rather than the [[2/1|octave]] being just. The octave is compressed by about 6.68{{c}}, a small but significant deviation. 10edf is [[consistent]] to the [[integer limit|7-integer-limit]], but not to the 8-integer-limit. In comparison, 17edo is only consistent up to the 4-integer-limit. This makes 10edf a suitable tuning perhaps in the [[5-limit]], but overcompressed in any other limits, as well as the no-5 13-limit, where 17edo is best at.

10 equal divisions of the perfect fifth (abbreviated 10edf or 10ed3/2) is a nonoctave tuning system that divides the interval of 3/2 into 10 equal parts of about 70.2 ¢ each. Each step represents a frequency ratio of (3/2)1/10, or the 10th root of 3/2.

Theory

10edf is related to 17edo, but with the perfect fifth rather than the octave being just. The octave is compressed by about 6.68 ¢, a small but significant deviation. 10edf is consistent to the 7-integer-limit, but not to the 8-integer-limit. In comparison, 17edo is only consistent up to the 4-integer-limit. This makes 10edf a suitable tuning perhaps in the 5-limit, but overcompressed in any other limits, as well as the no-5 13-limit, where 17edo is best at.

Subsets and supersets

Since 10 factors into primes as 2 × 5, 10edf contains 2edf and 5edf as subset edfs.
